If I have something like this... volatile long something_global = 0; long some_public_func() { return something_global++; } Would it be reasonable to expect this code to not break (race condition) when accessed with multiple threads? If it's not standard, could it still be done as a reasonable assumption about modern compilers? ...
I've seen this done before in various C++ libraries - namely Qt (QtCore, QtGui, etc.) and Irrlicht (irrlicht.h): // file - mylibrary.h #include "someclass1.h" #include "someclass2.h" #include "someclass3.h" // and so on... Obviously this exists for convenience - a programmer wishing to use the library only has to include one header i...

I've been learning C: it's a beautiful, well-thought-out language. However, it is so low-level that writing any sort of major project becomes tedious. What higher-level language has the most C-like syntax—but without all the clutter that you find in something like C++. Does one exist? ...
